on the drawings. Calculations shall substantiate that the design area used
in the calculations is the most demanding hydraulically. Water supply
curves and system requirements shall be plotted on semi-logarithmic graph
paper so as to present a summary of the complete hydraulic calculation. A
summary sheet listing sprinklers in the design area and their respective
hydraulic reference points, elevations, actual discharge pressures and
actual flows shall be provided. Elevations of hydraulic reference points
(nodes) shall be indicated. Documentation shall identify each pipe
individually and the nodes connected thereto. The diameter, length, flow,
velocity, friction loss, number and type fittings, total friction loss in
the pipe, equivalent pipe length and Hazen-Williams coefficient shall be
indicated for each pipe. For gridded systems, calculations shall show
peaking of demand area friction loss to verify that the hydraulically most
demanding area is being used. Also for gridded systems, a flow diagram
indicating the quantity and direction of flows shall be included. A
drawing showing hydraulic reference points (nodes) and pipe designations
used in the calculations shall be included and shall be independent of shop
drawings.

SPRINKLER SYSTEM INSTALLER QUALIFICATIONS
Work specified in this section shall be performed by the Sprinkler System
Installer. The Sprinkler System Installer shall be regularly engaged in
the installation of the type and complexity of system specified in the
Contract documents, and shall have served in a similar capacity for at
least three systems that have performed in the manner intended for a period
of not less than 6 months.

REGULATORY REQUIREMENTS
Compliance with referenced NFPA standards is mandatory. This includes
advisory provisions listed in the appendices of such standards, as though
the word "shall" had been substituted for the word "should" wherever it
appears. Applicable material and installation standards referenced in
Appendix A of NFPA 13 and NFPA 24 shall be considered mandatory the same as
if such referenced standards were specifically listed in this
specification. In the event of a conflict between specific provisions of
this specification and applicable NFPA standards, this specification shall
govern. All requirements that exceed the minimum requirements of NFPA 13
